Help needed! what heads are best for me?

I think it be a bit more head than you can use right now. And the crummy part is, purchasing and porting Edelbrock heads at this point will yeild similar specs at a near similar cost, just slightly less performance number wise, though for surley more suited to the build on hand.

If your looking to grow later, the Indy head would be good. I just see alot of port volume and it being a bit much for a 360 engine in it's current state.

Your stock head would need a full porting and new race valves to get where ya wanna go with this. It is probably cheaper than a new head, but it might leave some on the table. Worse if the porter doesn't do MoPar heads right.

For the price of fully ported J's, ...........
Under$1400 vs. OOTB Edelbrock heads @ $1431 @ summit and still needing a minor amount of attention??? Hummmmmmmm Verse $3500 for Indy heads.

In the end, you'll be slightly over cammed/underheaded as the otherway, to much head/undercammed.

Where do you want to end up?
